I was using version of repository.

i update version to last now

i compile and set new path in apache conf.

i try to restart apache:

server user / # apachectl graceful

the PID 93056 is freeze, i guess this is passenger process

server user / # sockstat -4 | grep http
www httpd 93056 3 tcp4 :80 *:
www httpd 93056 4 tcp46 :443 *:
www httpd 93056 5 tcp4 : :
root httpd 90976 3 tcp4 :80 *:
root httpd 90976 4 tcp46 :443 *:
root httpd 90976 5 tcp4 : :

try again:

server user / # apachectl graceful
server user / # sockstat -4 | grep http
www httpd 93056 3 tcp4 :80 *:
www httpd 93056 4 tcp46 :443 *:
www httpd 93056 5 tcp4 : :
root httpd 90976 3 tcp4 :80 *:
root httpd 90976 4 tcp46 :443 *:
root httpd 90976 5 tcp4 : :

i try with script

server user / # /apache22 restart
Performing sanity check on apache22 configuration:
Syntax OK
Stopping apache22.
Waiting for PIDS: 90976, 90976, 90976, 90976, 90976, 90976, 90976, 90976, 90976, 90976, 90976,
90976,
90976, 90976, 90976, 90976^C

see, the apache2 don't stop because PID 93056 is freeze and don't stop, the apache try to kill process until
I
give up and stop it.

when i kill process manually

server user / # kill -9 93056

the apache restart other process automatically

server user / # sockstat -4 | grep http
www httpd 93226 3 tcp4 :80 *:
www httpd 93226 4 tcp46 :443 *:
www httpd 93226 5 tcp4 : :
www httpd 93177 3 tcp4 :80 *:
www httpd 93177 4 tcp46 :443 *:
www httpd 93177 5 tcp4 : :
www httpd 93175 3 tcp4 :80 *:
www httpd 93175 4 tcp46 :443 *:
www httpd 93175 5 tcp4 : :
www httpd 93175 28 tcp4 :80 *:50271
www httpd 93174 3 tcp4 *:80 *:
www httpd 93174 4 tcp46 :443 *:
www httpd 93174 5 tcp4 : :
www httpd 93173 3 tcp4 :80 *:
www httpd 93173 4 tcp46 :443 *:
www httpd 93173 5 tcp4 : :
www httpd 93173 27 tcp4 :80 *:55683
www httpd 93172 3 tcp4 *:80 *:
www httpd 93172 4 tcp46 :443 *:
www httpd 93172 5 tcp4 : :
root httpd 90976 3 tcp4 :80 *:
root httpd 90976 4 tcp46 :443 *:
root httpd 90976 5 tcp4 : :

and all work fine.

The version of repository don't fix the problem.
